Application filed November 28, 1902. Serial No. 133,076.

' T 0 all whom it may concern:

State olihassacliiisetts, have invented certain new and useful Improvements in Solelf ounding h'lach'ines and I do hereby declare the follovl'ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to solo rounding machines of that class which comprise a pattern. a rounding knife, and means for relatively moving the pattern and rounding knife to cause the knife to travel around the pattern.

The invention is intended primarily as an improvement on the well-known Julian sole rounding machine, types of which are disclosed in llnited States Letters Patent to Gideon Julian, No. 528,128, dated October 23, 1894, and No- 663,656, dated December 11, 1900. In the machine shown in these patents the pattern upon which the sole is clamped is stationary and the rounding knife is mounted upon a support which is rotated to carry the knife around the pattern. W lnle my invention in its preferred form is embodied in a machine of this general type in which the relative movement of the pattern and knife is produced by moving the knife around a stationary pattern, as such a machine possesses certain advantages as to simplicity of construction and certainty of operation, and moreover can be used to cut soles from a strip or sheet of material containin sufficient stock for a number of soles, as we'll to cut a solo from a piece of mate rial containing only enough stock for a single sole, it is to be understood that broadly con sidered certain features of my invention are not limited to this type of machine but may be embodied in a machine in which the relative movement of the pattern and knife is produced by moving the pattern. It is also to be understood, that, except as specifically recited in the claims, the various features of my invention are not limited to any particular construction or arrangement of parts.

In the machine shown in the Julian patents above referred to, means are provided for moving the knife carrierduring the rounding operation to change the direction of the thrust or pull on the knife While the knife is passing around the ends of the pattern in order to prevent the knife from leaving the attern at these points. In these machines, iowcver, and in all other sole rounding inachines with'which I am familiar which. comprise a stationary pattern and means for moving the knife around the pattern, the thrust 'or pull on the knife while the knife is passing along the sides of the pattern is maintained substantially in the same direc ,tion being substantially parallel to the longitudinal axis of the pat-tern. For this reason there is a tendency for the knife to leave the pattern when passing around the prominent portions of the pattern-at the junction of the shank and forepart. In certain styles of soles the curve at the junction of the shank and forepart changes abruptly or the cuiyes of the foropart and shank meet at an angle. In rounding such soles, difficulty has been experienced in causing the knife to follow the pattern while travelin along the side of the pattern and it has cit or been necessary to run the sole rounding machine at a slow rate of speed or to allow theknife to leave the pattern when passing over the prominent portions at the junction of the shank and forepart and trim the sole to the exact shape of the pattern at a subsequent operation.

The object of. my invention is to provide a solo rounding machine in which the tendency of the knife to leave the pattern while passing around the prominent ortions at the junction of the shank and orepart is decreased, whereby soles which present shar curves or angles at the junction of the shan and forepart can be trimmed to the exact shape of the pattern Without decreasing the speed of the machine.

with this object in view my invention 0011- 9 templates providing a sole rounding machine comprising a pattern and a knife carrier movable about the pattern with means for. moving the knife carrier while the knife is traveling alongthe side. of the pattern to 100 moving the carrier to vary the direction of- 105 the thrust or pull on the knife as the knife is traveling along the side of the pattern are equally applicable to a sole rounding machine in which the relative movement of the pattern and knife to cause the knife to travel 110 ruled mourns for impuring additional move around tho pattern is produced by moving the pattern, and l therefore consider certain featuresi' 'of-my invention to consist in th s means hereinafter described and claimed, or their equivalents, for priulucing the desire: movements of the knife carrier to vary the direction of tho thrust or pull on the knife, Whether such means are embodied in :1 machine in which thrrelutiro movement of the pot-torn and knife to ca se the knife to travel around the puttcrn produced by moving the knife or arc embodied in it machine in which such i iv'e movement is produced by moving the pattern.

My invention also consists in certain clevices, combinations and arrangements of parts hereinafter described and claimed, the advantages ol'r-Jhich u'i ll be obvious to those skilled in the art from the following description.

ln order that n invention msy'be clearly understood, 1 e illustroi'J-s-d a orefcrrcd form thereof as embodied in the sole rounding machine disclosed in the patent to Julian No. 663,656, above referred to.

In the patented machine the knife carrier is pivotally mounted upon 2. support which is rotated to cor y the knife around the pat-- tern. The knife carrier has an inward and outward sliding movement with respect to its pivot and swung upon its pivot and moved inwardly and outwardly uring the rotation of the rotary support by means of crank having a direct wrist connection with the carrier and being secured to a shaft mounted in the rotary support and I i,r.l i'ng indli "nil-ently thereof. The oscillating IROVQIHBD imparted to the knife carrier by i318 crank are such that the direction of the thrust or pull on the knife is changed as the knife truvcis around the heel and toe of the pattern to cause the knife to follow the sharp curves at those portions of' the pattern. 'Wliile the knife is traveling along the sides of the pattern the oscillating movements imported to the knife ccrrior thc cmnk insinuin the thrust or pull on the knife in a direcsubstontislly parallel with the longiulinal oi the p ru.

to-Tary the ou'ection of the thrust on the knife the knife is traveling slon th sidcsof the stteru so as to (locrcsie th tendency of te knife to leave the pattern while passing around thc prominent potions of the pattern at the junction of the anti forepu'rt and thereby enable the I to trim soles which present sharp r angles at such points, I have proments to the knife, carrier. In thcillus trstcclcinbodiment of my invention these additional movements are imported to knife carrier by mo ving the pivot of the carrier while the knife traveling along the sides of the pattern. To enable the pivot of the carrier to be moved, I hove mountc rl it upon an arm supported from the rotary support and for moving the pivot of the knife carrier .1 have provided a cam and suitable connections between the cam and the arm upon which the pivot is mounted. The com in the machine illustrated is stationary and the connections between the com and the arm upon which the pivot of the knife can ricr mounted consist of a lever pivotally mounted upon the rotary su port having one cud in engagement with t e cam and. the other end connected to the arm by means of a link. The shape of the stationary cam and the arrangement or. the connections are such that the knife carrier is oscillated about the wrist connection with the crank to change the direction of the thrust 0r ull on the knife as theknife passes aroun the short curves or angles st the junction of the slum and lorepart of the pattern so as to overcome any tendency of the knife to leave the pattern at these oints. tween the stationar cam and the pivot ol the knife carrier are adjustable so that the requisite amount of movement can be imparted to the knife carrier to suit the shape of the sole which is'to be trimmed.
